27th September 2018 - The Global TAC (Tri-acetyl Cellulose) Film Market is segmented on the basis of types, application, and geographical region. TAC stands for tri-acetyl cellulose, also known as triacetate, CTA, Cellulose triacetate. It is a chemical compound manufactured from cellulose and a source of acetate esters, characteristically acetic anhydride. It is classically used for the creation of fibers and film base. The TAC film is a polymeric film in which all or a predominant portion of the film is cellulose triacetate. Tri-acetyl cellulose (TAC) films are widely used as a protective film for polarizers because it has high light transmittance, low birefringence, high moisture permeability, high uniformity and good curling property.

Plasticizing agents have long been known to increase the physical properties of solvent cast cellulose triacetate (also called triacetyl cellulose or TAC) polymeric films. TAC polymers have a cellulose chain backbone with varying degrees of acetylation. TAC can range in substitution from approximately 2.4 to 3 acetyl substitution points on the cellulose backbone. Other substitutions on the cellulose backbone could be hydroxyl, propyl or butyl groups. TAC tends to be high in polymer molecular weight. This is due to the enormously large cellulose chains it is formed from. TAC cannot be thermally extruded, as it does not possess a melting point. TAC is a very good polymer for forming amorphous polymer sheet.
The TAC film plays an active role in optical compensation of LCDs as well as protection of polarizers. The out-of-plane birefringence of the TAC film can be controlled by additives, and the in-plane birefringence can be controlled by stretching. Coating a discotic material on the TAC film gives a supplementary optical compensation layer.
